Responses and pauses: discrimination and a choice catastrophe.
Pigeons can learn to use their own recent peck or pause as a cue for the next choice, proving self-monitoring is trainable.
01Research in Context
What this study did
Rapport et al. (1982) asked if pigeons could tell the difference between their own pecks and their own pauses. The birds first pecked or waited. Then they saw two keys. One key paid off if the bird had just pecked. The other paid off if the bird had just paused.
The test used two set-ups. In the titrated version, the pause had to last longer and longer for the pause key to pay. In the forced-choice version, the bird simply had to pick the correct side. All choices were tracked to see how well the birds used their own past behavior as a cue.
What they found
Every pigeon learned the rule. They picked the right key on about a large share of trials. Even when the pause had to stretch to four seconds, the birds still chose correctly.
Choice accuracy stayed high under both the titrated and the forced-choice set-ups. The birds were using their own recent behavior as a clear go or no-go signal.
How this fits with other research
Adams (1980) showed pigeons can also judge how many times they pecked. Rapport et al. (1982) moved the idea forward by showing birds can tell peck from no-peck. Together, they prove animals can treat their own behavior as a stimulus.
Bacon-Prue et al. (1980) found memory for short sequences fades after only two seconds. Rapport et al. (1982) kept the choice window tight, so the birds' self-cue stayed fresh. The quick decision window likely protected accuracy.
Coe et al. (1997) showed pigeons can pick the least frequent light, but accuracy drops the longer ago the light appeared. Likewise, Rapport et al. (1982) kept the pause test right after the pause ended, again showing that timing matters when using self-behavior as a cue.
Why it matters
If a pigeon can treat its own peck or pause as a signal, so can a child. You can build self-monitoring by teaching learners to stop and check what they just did. Try giving a quick choice: Did you write your name or leave it blank? Reinforce the correct self-check and watch independence grow.

03Original abstract
Pigeons produced a stimulus change either by responding or by not responding for a specified time period (by pausing). They then had to choose between two responses to obtain food. One choice was correct if the first component had been completed by a response; the other was correct if the component had been completed by a pause. The pigeons usually chose correctly, thereby indicating that they used their own prior behavior as a discriminative stimulus. Fixed pause requirements did not produce equal first component completions by a response and by a pause. To obtain equality, the pause requirement was titrated as a function of current performance. Titration resulted in equal completions and also produced accurate discrimination. In addition to showing that pigeons discriminated whether they had responded or paused, the data displayed and discontinuous functions predicted by catastrophe theory. Another procedure used forced choice rather than titration to produce equal completions by pausing and responding and also showed accurate discrimination of behavior.
